Tomato End Rot?
I'm new to gardening so I think that's what it's called. I planted 18 San Marzano tomato plants (did I know that if you plant 18 seeds, you get 18 plants? - Call me lucky or dumb!) , and I see a brown circle on the bottom of some of these little green tomatoes.. Within several of them, I see some tomatoes have it, and some don't. And two others, all tomatoes have it. :( I pulled off the brown ones - was that the right thing to do? How can I prevent the others from getting this? Is it contagious? I'm assuming they just stop growing, right, and are inedible?
On another note, due to extremely heavy rain the other day, one plant in a large garbage pail had so much water in it, I had to scoop out a bunch of water. Poor thing looks like it's done! The leaves look super droopy... Is there something I can do to bring it back to life other than not giving it anymore water?
I so welcome and appreciate your advice!
PS Sorry the pic is so big. Not sure how to make it smaller!
